TypeError: Cannot read properties of undefined (reading 'util') in timestamp.js when using ts-node

[HephX]

I'm running my TypeScript project with ts-node, and I'm getting the following error in the generated timestamp.js from jito-ts:

TypeError: Cannot read properties of undefined (reading 'util')
    at timestamp.js:86:23

// offending line:
if (minimal_1.default.util.Long !== long_1.default) {

minimal_1.default is undefined, even though protobufjs/minimal is correctly installed.
The esModuleInterop flag is enabled in my tsconfig.json.

This setup used to work — possibly this is related to a recent update of protobufjs or Node?
Thanks in advance!
